Is it reasonable to drop the cost of Chaos Armour for these boys by one point to +1/+2 points?

At present, a fully kitted out CD Warrior is 14 pts (Chaos Armour,shield and a great weapon), which is the cost of an Obsidian Guardsman without a shield. Given the higher WS, and S of the Obsidian Guard and their special abilities, the cost of the Chaos Armour for the Warriors should be dropped slightly to compensate.

What about making the basic chaos dwarf a "slaver".Just steal the slaver rule from the dark elf corsairs and you're good to go.

Chaos dwarves as a race, are slavers. Giving core warriors the slaver rule may encourage people fielding chaos dwarves, in a chaos dwarf army.I wouldn't give it to the guys with blunderbusses, it's obvious they're not taking prisoners. Likewise, Obsidian Guards have a task at hand other than slaving.

I don't recall the text, but I think the slaver rule lets you force your opponent to re-roll his flee distance when fleeing from the slavers.
